6 + ( 2 − 3 ( 4 ) ) + 1 /( 5 ) ( 2 ) − 4

6 + (2 - 3 (4) )+1 / (5) (2) - 4 = -1 /2

Step-by-step explanation:

6 + (2 - 3 (4) )+1 / (5) (2) - 4

Using the BODMAS rule, we can simplify the expression in the following way, like, we have to do the operation inside the brackets first, then division, multiplication, addition and then subtraction.

= 6 + (2 - 3 (4) )+1 / (5) (2) - 4  [operation inside the brackets]

= 6 + (2 - 12) )+1 / (5) (2) - 4  

= 6 + (-10) )+1 / (10) - 4

=   6 + 1 -10 / (10) - 4

=  7 - 10/ 6

= -3 / 6

= -1/2
